Similarly, people often don't like it when insurers track and score their driving. However, this allows insurers to offer lower insurance fees to more people by _not_ offering lower insurance fees (or instead charging higher fees) to people that are driving in a risky manner. This does of course assume a competitive market for insurance but I think in most countries that's a reasonable assumption.
There's nothing fairer than user-pays, especially when users can choose to pay less by changing their behavior.

I think it's probably also correct to say that New Zealand could sustain a larger passenger rail network if made the right investments. For example, Auckland <-> Hamilton <-> Tauranga could profitably support at least a few trains per day in each direction... _if_ it was electrified, with passing loops where needed, and with well-sited stations, and with the ability for trains to run into Britomart or at least Newmarket (both being stations close to central Auckland). However, there's a chicken and egg problem: unless you make investments like that, the service you can offer will be pretty crap and no one will want to ride your slow trains.

Jevon's Paradox means that the demand for intelligence will keep rising as the cost drops, so I can't help but expect a steady increase in the economic value of land _when used for AI_. It'll take a long time before it exceeds the economic value of land when used for human subsistence, but the growth curves are not pointing in encouraging directions.

Regarding Boston, the interesting thing is that it used to be connected to the Merrimack via the Middlesex Canal. My understanding is that this is silted up now (which you presumably already know) but it shows how many more connections we used to have.

Clearly, Alon's title uses wonkish terminology and would have benefited from a title that was more easily understood by people unfamiliar with the field. I think it's fair to say that you're not the target audience.

You can see the same effect with railways and aeroplanes. There's definitely plenty of operational costs, but the capital costs are relatively high so you want to keep your capital goods (the railways/trains/planes) active all the time even if you only make a tiny profit on each service. However, these businesses often only pan out if they can attract high-margin customers (e.g. business class flyers).

To my eyes it seems very fair to offer a product at (appromimately) the same real price for everyone in the world, and let people choose whether or not to buy it.
And for what it's worth, commodities are also priced at what the market can bear, not at their marginal cost of production. It's just that competition pushes those prices down very close to the marginal cost. This course has competition too, in the form of all the other articles and tutorials that are available free on the internet. It's not like this course is the only gate to otherwise-inaccessible knowledge.

Among other things, involuntary porn is a massive violation of privacy. Maybe some individuals don't feel that this area needs to be private, but what matters is whether the _victim_ wants it to be private. If your solution is "the victims shouldn't make such a big deal of this", that's wishful thinking not a solution.

Of course, immigration-driven growth is great! But for people on the ground, what matters is GDP per capita, not total GDP.
Note that you _are_ legally required to pay your annual ACC levies, which fund no-fault cover for injuries. However that doesn't cover property damage.
